Quartz和Spring：动态调度

我有一个Web服务，它可以完成某项工作 . 该作业是一个Java类，它扩展了Quartz Job接口

public class StartJob implements Job {
    private String jobId;
    private DAO dao;

    public void execute(JobExecutionContext context) throws JobExecutionException {

        JobDataMap dataMap = context.getMergedJobDataMap();

        //some logic here
    }

    // getters and setters
}

我还公开了一个API，它接收一个jobId一个cron表达式，并安排一个具有收到id的新StartJob . 这是我的 Spring configuration ：

@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(basePackages = { "persistence.dao" })
@ImportResource({"spring-quartz-context.xml"})
public class BeanConfig {
    //wired from the xml
    @Autowired JobDetailFactoryBean jobDetailFactory;
    @Autowired CronTriggerFactoryBean cronTriggerFactory;

    @Bean
    public SchedulerFactoryBean schedulerFactoryBean() {
        SchedulerFactoryBean bean = new SchedulerFactoryBean();
        bean.setApplicationContextSchedulerContextKey("applicationContext");
        bean.setSchedulerName("MyScheduler");
        Map<String, Object> schedulerContextAsMap = new HashMap<String, Object>();
        bean.setSchedulerContextAsMap(schedulerContextAsMap);
        // quartzproperties not reported
        bean.setQuartzProperties(quartzProperties());

        return bean;
    }

    //other bean definitions

}

和spring-quartz-config.xml

<bean name="complexJobDetail"
    class="org.springframework.scheduling.quartz.JobDetailFactoryBean">
    <property name="jobClass" value="jobs.StartJob" />
    <property name="durability" value="true" />
</bean>

<bean id="cronTrigger" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
    <property name="jobDetail" ref="complexJobDetail" />
    <property name="cronExpression" value="0/5 * * ? * SAT-SUN" />
</bean>

What I want to do 类似于（伪代码）

JobDetail job = jobDetailFactory.getObject();
job.setName(aGeneratedUUID);
CronTrigger trigger = cronTriggerFactory.getObject();
trigger.setCronExpression(aDynamicCronExpression);

scheduler.schedule(job, trigger);

但问题是我无法更改作业名称，因此， only the first job is scheduled . 第一个作业使用JobDetailFactoryBean的名称（complexJobDetail）作为名称 .

我在这里失踪了什么？这个配置是否正确？从工厂检索的作业和触发器是同一个类的新实例，还是同一个类实例？
